Multisite Subdirectories Not Working

When I try to make a subblog on my site http://www.collegiateconsumption.com I get an error when I try to access the dashboard. Am I doing something wrong when I set it up? I go to add new site, type in /test for example (collegiateconsumption.com/test), name it "test," and then add the admin email. When I then go to view dashboard once the site is created I get a redirect error. Not sure what I am doing wrong!
